winbio.h header file functions are disabled?

Question

i am using VS 2010 in windows 7 express edition.

i also tried to get a winbiocapturesample function from this headerfile.but i have a problem to use winbio.h functions.this header placed in microsoft sdk v7.0a.

i will include that header file into my solution,after the below condition functions are disabled.

#if (NTDDI_VERSION >= NTDDI_WIN7)

but i am using windows 7 only.can anyone tell what NTDDI_VERSION,why its not working.

if i try to debug error C3861: 'WinBioOpenSession': identifier not found

but,the 'WinBioOpenSession' is in that headerfile after check the above condition.

Thank in advance.

The compiler can't predict what Windows version you're targeting. You have to set that. NTDDI_VERSION should be set to NTDDI_WIN7 if you want to target Windows 7.
